Distribution of promoter methylation level and number of microRNA target sites in genes by their expression broadness. (a) Negative correlation between promoter methylation level (mCG/CG) in human cell H1 and expression broadness. (b) microRNAs preferentially target the genes with intermediate expression broadness.
